WASHINGTON (AP) – Libertarian presidential candidate Gary Johnson says he, “blanked” when he was asked about the name of Syria’s largest city.

Johnson said in a statement that he thought Aleppo was an acronym when asked about it on the television show “Morning Joe” Thursday morning. Johnson responded, “What is Aleppo?” That response quickly went viral.

Johonson said in his statement that he, “blanked,” and added, “It happens and it will happen again during the course of this campaign.”

Johnson is in the midst of a media blitz in New York City as he tries to reach 15 percent in national polls. That’s the threshold needed for him to have a spot in the first presidential debate on Sept. 26.
